【问题讨论】：

您在每一行中使用相同的 ID。 $("#client") 将始终选择第一个。改用类，$(this).closest("tr").find(".client") 选择与按钮在同一行中的输入。
$(document).on('click', '.btn_add', function(){ var client = $(this).closest("tr").find(".client_add") .text(); var contact = $('.contact_add').text(); var note = $('.note_add').text(); var status = $('.status_add').val(); var id_table = $('.id_table_add').text();
你在调用ajax，因为ajax是异步的，不能执行多个异步调用。您必须在第二个 ajax 调用上设置 async = false 。您可以查看此链接stackoverflow.com/questions/1639555/…
哈，没关系！谢谢！

谢谢！

$(document).on('click', '.btn_add', function(){
var client = $(this).closest(".formulaire").find('.client_add').text();  
var contact = $(this).closest(".formulaire").find('.contact_add').text();  
var note = $(this).closest(".formulaire").find('.note_add').text();
var status = $(this).closest(".formulaire").find('.status_add').val(); 
var id_table = $(this).closest(".formulaire").find('.id_table_add').text();
